Nick Malik (Microsoft) asks for feedback input on a workflow component he is working on. Are groups responsible for business processes?
If you are assuming that one instance of the workflow engine handles the entire business process, then perhaps you can afford to be prescriptive. But if you want to allow federation or interoperability between workflow engines, then you probably want to allow some flexibility about the handover from one engine (instance) to another. For example, this might mean that engine A regards the entire group as responsible for something, while engine B manages intra-group delegation and accountability. And this also seems to reflect more accurately the way management processes often work in large organizations.
